''Horshamosaurus'' is a genus of herbivorous ankylosaurian dinosaur from the Early Cretaceous of England. ==Discovery== In 1985, at the marl quarry of the Rudgwick Brickworks Company near Rudgwick in West Sussex, fossils were dug up of dinosaurs. These were secured by two volunteers of the Horsham Museum: Morris Zdzalek and Sylvia Standing. After 1988, the finds were exhibited in the museum as ''Iguanodon'' bones. Subsequently neurologist William T. Blows, an amateur paleontologist who already had extensively published on the subject of armoured dinosaurs, determined that the bones were not iguanodontian but instead represented ankylosaurian remains. In 1996, on basis of the finds, a new species of the genus ''Polacanthus'', ''Polacanthus rudgwickensis'', was named and described by Blows. The specific name refers to the provenance from Rudgwick.〔Blows W.T. (1996) "A new species of ''Polacanthus'' (Ornithischia; Ankylosauria) from the Lower Cretaceous of Sussex, England". ''Geological Magazine'', 133 (6): 671–682〕 The material, holotype HORSM 1988.1546, was found in a layer of gray-green marl beds of the lower Weald Clay Formation dating from the Barremian age, over 125 million years old. It is fragmentary and includes two incomplete dorsal vertebrae, part of a front tail vertebra, bone fragments of other vertebrae, a partial left scapulocoracoid of the shoulder girdle, the distal end of a humerus, a nearly complete right tibia, rib fragments, and two osteoderms.〔 In 2015, Blows made it a separate genus ''Horshamosaurus'', the generic name referring to Horsham. Its type species is ''Polacanthus rudgwickensis''. The ''combinatio nova'' is ''Horshamosaurus rudgwickensis''.〔Blows, W.T., 2015, ''British Polacanthid Dinosaurs – Observations on the History and Palaeontology of the UK Polacanthid Armoured Dinosaurs and their Relatives'', Siri Scientific Press, 220 pp〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Horshamosaurus」の詳細全文を読む スポンサード リンク
